Nagios Support Forum

Does a local user called nagios has root privileges (defined in /etc/sudoers?) to run commands such as "/etc/init.d/nagios start"? No password is required to run them as nagios?

Hi,

When Nagios XI is installed a local nagios account is created and this account has to be able to restart services and run the backend scripts. This is all defined in the /etc/sudoers file. Also, depending on what OS you are using some of those entries such as ''/etc/init.d/nagios start' are there for backward compatibility.

Let us know if you have any other questions.

If password of nagios user must be changed because of implementing security policy, will it make nagios services and scripts fail to run or malfunction?

Hi,

There isn't a password set on the default nagios account. As mentioned, this will cause issues with starting and stopping services.
Hope that helps answer your question.
